Secure NFC Payment via Physical Proximity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device payment services using QR codes lack assurance that the secure communication will be limited to the intended user, as malware can capture and misuse the code, allowing unauthorized access.
Innovation Solution
A system comprising a transmitting device, an intermediary device, and user devices that encrypt and decrypt communications using physical proximity, ensuring secure transactions by modifying QR codes and encryption keys, allowing only proximate users to access sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If QR codes are used for mobile device payment services, then transaction convenience is improved, but security reliability deteriorates because malware can capture and misuse the codes
Solution Approach 1:
The patent introduces NFC technology as an intermediary between the QR code and the payment transaction. Instead of directly using QR codes that can be captured by malware, the system uses NFC as a mediator that enables contactless communication only when devices are physically close, adding a layer of security while maintaining convenience
Solution Approach 2:
The patent transitions from two-dimensional QR code scanning to three-dimensional spatial proximity verification through NFC. The NFC technology requires physical closeness (within a few inches) between devices to establish communication, adding a spatial dimension to the authentication process that prevents remote malware capture
2Productivity
If QR codes are used for secure communication, then communication efficiency is improved, but access control reliability worsens because any user with the code can access the information
Solution Approach 1:
NFC acts as an intermediary that verifies the physical presence and identity of the device before allowing access to the QR code or payment information. This mediator ensures that only the intended recipient who is physically present can complete the transaction, improving access control reliability
Solution Approach 2:
The system performs preliminary verification of device identity and proximity through NFC before allowing the QR code to be read or the payment to be processed. This preliminary action prevents unauthorized access by ensuring the device is legitimate and physically present before any sensitive information is transmitted

AI summary
Systems and methods may provide for implementing a secure communication using physical proximity. In one example, the method may include transmitting an encrypted first communication including a sensitive information file, decrypting the encrypted first communication to generate a decrypted first communication including the sensitive information file, displaying the decrypted first communication, capturing a version of the decrypted first communication displayed on the intermediary device, and extracting the sensitive information file at a user device.
